' ANTICREEPER FOR RAILROAD RAILS.

Specification of Letters Patent.

Patented July 31, 191?.

Application filed May 7, 1917. Serial No. 186,874.

To all whom it may concern Be it known that I, lVILLrA M M. MITCHELL, acitizen of the United States, and a resident of Louisville, county ofJefferson, and State of Kentucky, have invented certain new and usefulImprovements in Anticreepers for Railroad-Rails, of which the followingis a specification.

The invention relates to anti-creepers or rail anchors for preventingthe longitudinal movement of railroad rails. To avoid cutting,perforating or otherwise weakening the "rail to receive attaching rivetsor the like. rail anchors now in use are held in position by a frictiongrip of one sort or another. But it has been found difficult to providerail anchors of this-sort, which will effectively maintain their grip onthe rails under all working conditions.

The present invention seeks to overcome the difficulties above noted andto provide a rail anchor adapted to abut against the tie and which issolidly united to the rail by welding or fusing without weakening themetal body thereof. Further objects of the invention are to provide arail anchor which can be manufactured at very low cost and which can bereadily and inexpensively applied to the rails by welding or fusing.

The invention consists'in the features of improvement hereinafter setforth, illustrated in diflerent preferred forms in the accompanyingdrawings and more particularly pointed out in the appended claims.

In the drawings Figure 1 is a plan view of one form of the presentinvention. Fig. 2 is a side View thereof. Fig. 3 is an enlarged sectionon the line 33 of Fig. 1. Fig. 4 is a view similar to Fig. 3illustrating a slightly different manner of applying the rail anchor.Figs. 5 and 6 are plan views illustrating modifications. Fig. 7 is across section illustrating another modification.

The improved anchor is constructed of forged or rolled ironor steel andis preferably of simple form comprising only a tieabutting portion and aportion at an angle thereto extending beneath the rail base andoutwardly beyond the edge portion thereof and securely fused or weldedto the edge portion of the rail base. Such anchors can be inexpensivelymade from rolled iron or steel bars of different shapes or indeed frompieces of scrap.

The form shown in Figs. 1 to 4 inclusive comprises a verticallydisposed'tie-abutting member or flange 1 and a vertically disposedflange 2 which extends rearwardly beneath the edge of the rail base 3and the upper part of which is welded or fused to the rail.

part or lip 5 which extends over the vertical edge face of the railbase. The anchor can be welded or fused to one of the base flanges ofthe rail before the rail is laid, but preferably it is applied to therail when the latter is-in position in the track. I When this is done aportion of the base flange of the rail adjacent the tie, is heatednearly to the fusion point by a portable heating device such as anoXy-acetylene torch. The anchor is then applied in position with themember or flange 1 abutting against the tie 6 and with the shoulder 4;extending beneath and 1n engagement with the lower horizontal face ofthe rail base, but preferably the inner ,7 I

face of the upwardly projecting portion or lip 5 is spaced to a slightextent from the adjacent vertical edge of the rail base. The adjacentportions of the lip 5 and edge of the rail base are then securely fusedtogether by a fillet of metal as indicated at a in Fig. 3, the metalfillet being solidly united or in corporated with the metal of theadjacent portions of the rail base and anchor.

If desired, the fillet may be formed by using the oxy-acetylene torch tofuse adjacent portions of the edge of the rail base and of the lip orportion 5 of the anchor, but preferably the fillet is fused in part froma steel pencil or rod and run into the space between these parts. Ifdesired, the portion or lip 5 may be omitted and the uniting filletformed between the edge of the rail base and the horizontal face of theprojecting upper edge portion of the member 2, as indicated at a in Fig.4.

, In this Way, the anchor is readily and soldidly secured in positionWithout in any way weakening the metal body of the rail. Obviously too.the anchor is permanently it cannot be discontraction or by of the rail.away from the be dislodged by the poundaud vibration due to the passageof city traliic over the rail.

he anchor thus efiectively prevents ping of the rail in the directionindicatcd by the arrow in Fig. 2. The reaction thrust of the rail on theflange or member sisted the flange or member 2 which forms a bracebetween the tie abut merit and the rail engaging portion that extendsbeneath the edge of the rail base. refera cree oly, boss Z) of metal iswelded or c to the upper face of the rail base and to the upper portionof the anchor at a point adjacent the tie. This boss may be formed inpiece with the anchor before the latter is applied, but it is preferablybuilt up when the anchor is applied by fusing a steel rod or pencil.lhis boss serves to aid in resistingthe reaction thrust of the tie uponthe anchor and thus strengthens the welded joint. Preferably also, asmost plainly shown in Fig. l, the tie-engaging abutment member 1 extendsboth beneath and to one side of the rail base to a. substantially equalextent on opposite sides of the welded joint and the latter is therebyrelieved of horizontal twisting strains.

The term shown in 5 is similar to that previously shown and describedexcept that tie-abutment member 7 extends on one side only or" themember 2 so that the anchor can readily formed of a section of an anglebar. The form shown in Fig. 6 is like that shown in Figs. 1 and 5 exceptthat it is formed of a section of channel bar. The tie-abutment member 8extends entirely honest the rail base and the rearwardly extendingflanges or members 9 are welded to the opposite side edges thereof.

Preferably as shown in Figs. 1, 5 and 6 he portions fused or welded tothe edge of 1c raillbase are beveled or inclined at their eds, shown, sothat they will engage and efiect the wheels of a derailed car that mightotherwise break off and destroy the anchors.

The form shown in Fig. 7 comprises a depending tie-engaging abutment 11,a hori zontal rail engaging portion or member 10 and an intermediatehollow bracing portion 12. The portion 10 extends beneath the rail baseand projects outwardly beyond the edge thereof and is provided with anupturned part or lip 13 and preferably also with an integral boss ll. Inapplying the anchor the portion 13 is spaced slightly from the adjacentvertical edge of the rail base and is welded thereto by a fillet asindicated at c. The edges of the boss i i are welded to. the upper faceof the rail base by fillets (Z.
